Organometallic Catalysis

The Monsanto acetic acid procedure is a carbonylation reaction utilising an organometallic catalyst. It was first created by Monsanto in the 1970s with the purpose of producing acetic acid commercially from methanol. Dual catalysis is used in the process, utilising HI and [RhI 2 (CO) 2]-as a co-catalyst. Early in the 1950s, German scientist Karl Ziegler developed a process for producing nearly fully linear HDPE at low pressures and low temperatures in the presence of intricate organometallic catalysts. Heterogeneous catalysts or organometallic catalysts, like palladium on carbon. These phrases are employed because the homogeneous type of reaction, in which catalysis occurs at the catalyst's surface, occurs with the catalyst and reaction substrates being in the same phase but not in the heterogeneous type.
